Turning into plastic is an exothermic reaction. That's what's heating the tank.

It is also a slower exothermic reaction. Which makes it possibly manageable.

		Than what? Genuinely curious. I thought that the main exothermic thing monomers did was polymerization or combustion, and we're really hoping to prevent the latter.
